I'd like to suggest that the co op Tbolt be like the campaign version, with a magazine.
Co-op snipers shouldn't have a forced scope, at least in Easy/Normal difficulties (that should help noobs). I don't think that NPCs would complain...
Then again, ND doesn't give a **bleep** about Co-op.
Mega bomb is all I agree with really, and well I will always see riot shield as useless when all NPCs have hawkeye accuracy even with the micro and kal even when ur behind a shield.
Mega bomb should be increased damage, but every other kickback has its uses and I've used em all every now and then and found them to work well under the right conditions.
